FIELD: chemistry.
SUBSTANCE: invention relates to a composition of a biodegradable ceramic fibre for high-temperature heat insulation. The composition of the biodegradable ceramic fibre for high-temperature heat insulation contains the following components in wt %: SiO2 - 58-67; CaO - 26-34; MgO - 2-8; Al2O3 - 0-1; B2O3 - 0.2-1.1; B2O3+Na2O - 0.3-1.1; admixtures, selected from TiO2 and Fe2O3 - less or equal to 1.
EFFECT: increased heat resistance of products.
